    No full text
    Abstract — This paper automates the design and implementation of students ’ attendance management system, taken into consideration easy access and time saving. The system will be used in faculty of computing and information system (FCIT) at King Abdulaziz University (KAU). Radio Frequency Identification (RFID) and wireless technology are two technologies which will be applied as infrastructure in the indoor environment. University Based Services (UBS) and tag IDs of the RFID are being used in this paper, in order to determine the attendance list for academic staff. Once the academic staff enters a classroom, he will be able to register student’s presence. Therefore, an academic system for identifying and tracking attendance at computing college at KAU will be described, and hybrid RFID and Wireless LAN (WLAN) technologies will be implemented in FCIT academic environment

    Distributed User Interfaces: Models, Methods and Tools

    Distributed User Interfaces (DUIs) have recently become a new field of research and development in Human- Computer Interaction (HCI). The DUIs have brought about drastic changes affecting the way interactive systems are conceived. DUIs have gone beyond the fact that user interfaces are controlled by a single end user on the same computing platform in the same environment. This new interaction mechanism affects the way these novel systems are designed and developed. New features need to be taken into account from the very beginning of the development process and new models, methods, and tools need to be considered for the correct development of interactive systems based on Distributed User Interfaces. Therefore, the goal of this workshop is to promote the discussion about the emerging topic of DUIs, answering a set of key questions regarding their development: How current UI models can be used or extended to cover the new features of DUIs? What new features should be considered and how should they be included within the development process? What new methods and methodologies do we need to develop DUIs in a correct way following the quality standards for interactive systems

    AimThe SARS-CoV-2 pandemic has provided a unique opportunity to explore the impact of surgical delays on cancer resectability. This study aimed to compare resectability for colorectal cancer patients undergoing delayed versus non-delayed surgery.MethodsThis was an international prospective cohort study of consecutive colorectal cancer patients with a decision for curative surgery (January-April 2020). Surgical delay was defined as an operation taking place more than 4 weeks after treatment decision, in a patient who did not receive neoadjuvant therapy. A subgroup analysis explored the effects of delay in elective patients only. The impact of longer delays was explored in a sensitivity analysis. The primary outcome was complete resection, defined as curative resection with an R0 margin.ResultsOverall, 5453 patients from 304 hospitals in 47 countries were included, of whom 6.6% (358/5453) did not receive their planned operation. Of the 4304 operated patients without neoadjuvant therapy, 40.5% (1744/4304) were delayed beyond 4 weeks. Delayed patients were more likely to be older, men, more comorbid, have higher body mass index and have rectal cancer and early stage disease. Delayed patients had higher unadjusted rates of complete resection (93.7% vs. 91.9%, P = 0.032) and lower rates of emergency surgery (4.5% vs. 22.5%, P ConclusionOne in 15 colorectal cancer patients did not receive their planned operation during the first wave of COVID-19. Surgical delay did not appear to compromise resectability, raising the hypothesis that any reduction in long-term survival attributable to delays is likely to be due to micro-metastatic disease
